[BibTeX] [Abstract] [Download PDF]

Abstract The specification of requirements and tests are crucial activities in automotive development projects. However, due to the increasing complexity of automotive systems, practitioners fail to specify requirements and tests for distributed and evolving systems with complex interactions when following traditional development processes. To address this research gap, we propose a technique that starts with the early identification of validation concerns from a stakeholder perspective, which we use to systematically design tests that drive a scenario-based modeling and analysis of system requirements. To ensure complete and consistent requirements and test specifications in a form that is required in automotive development projects, we develop a Model-Based Systems Engineering (MBSE) methodology. This methodology supports system architects and test designers in the collaborative application of our technique and in maintaining a central system model, in order to automatically derive the required specifications. We evaluate our methodology by applying it at KOSTAL (Tier1 supplier) and within student projects as part of the masters program Embedded Systems Engineering. Our study corroborates that our methodology is applicable and improves existing requirements and test specification processes by supporting the integrated and stakeholder-focused modeling of product and validation systems, where the early definition of stakeholder and validation concerns fosters a problem-oriented, iterative and test-driven requirements�modeling.

Using synthesis- and AI-planning-based approaches, recent works investigated methods to support engineers with the automation of design, planning, and execution of multi-robot cells. However, real-time constraints and stochastic processes were not well covered due, e.g., to the high abstraction level of the problem modeling, and these methods do not scale well. In this paper, using probabilistic model checking, we construct a controller and integrate it with reinforcement learning approaches to synthesize the most efficient and correct multi-robot task schedules. Statistical Model Checking (SMC) is applied for system requirement verification. Our method is aware of uncertainties and considers robot movement times, interruption times, and stochastic interruptions that can be learned during multi-robot cell operations. We developed a model-at-runtime that integrates the execution of the production cell and optimizes its performance using a controller-based AI system. For this purpose and to derive the best policy, we implemented and compared AI-based methods, namely, Monte Carlo Tree Search, a heuristic AI-planning technique, and Q-learning, a model-free reinforcement learning method. Our results show that our methodology can choose time-efficient task sequences that consequently improve the cycle time and efficiently adapt to stochastic events, e.g., robot interruptions. Moreover, our approach scales well compared to previous investigations using SMC, which did not reveal any violation of the requirements.

In automotive production cells, complex processes involving multiple robots must be optimized for cycle time. We investigated using a symbolic GR(1) controller synthesis algorithm for automating multi-robot task planning. Given a specification of the order of tasks and states to avoid, often multiple valid strategies can be computed; in many states there are multiple choices to satisfy the specification, such as choosing different robots to perform a certain task. To determine the best choices under the consideration of movement times and probabilities that robots may be interrupted for repairs or corrections, we investigated combining the execution of the synthesized controller with Monte Carlo Tree Search (MCTS), a heuristic AI-planning technique. We present our approach by the example of a multi-robot spot welding cell and report on experiments showing that the approach (1) can reduce cycle times by choosing time-efficient movement sequences and (2) can choose executions that react efficiently to interruptions by choosing to delay tasks that, if an interruption of one robot should occur later, can be reallocated to another robot. Most interestingly, we found, however, that (3) in some cases there is a conflict between time-efficient movement sequences and ones that may react efficiently to probable future interruptions?and when interruption probabilities are low, increasing the time allocated for MCTS, i.e., increasing the number of iterations may not perform better.

[Context {&} Motivation] Due to the managerial, operational and evolutionary independence of constituent systems (CSs) in a System of Systems (SoS) context, top-down and linear requirements engineering (RE) approaches are insufficient. RE techniques for SoS must support iterating, changing, synchronizing, and communicating requirements across different abstraction and hierarchy levels as well as scopes of responsibility. [Question/Problem] We address the challenge of SoS requirements specification, where requirements can describe the SoS behavior, but also the behavior of CSs that are developed independently. [Principal Ideas] To support the requirements specification in an SoS environment, we propose a scenario-based and iterative specification technique. This allows requirements engineers to continuously model and jointly execute and test the system behavior for the SoS and the CS in order to detect contradictions in the requirement specifications at an early stage. [Contribution] In this paper, we describe an extension for the scenario-modeling language for Kotlin (SMLK) to continuously and formally model requirements on SoS and CS level. To support the iterative requirements specification and modeling we combine SMLK with agile development techniques. We demonstrate the applicability of our approach with the help of an example from the field of e-mobility.

Cyber-physical systems are found in many areas, such as manufacturing, or smart cities. They consist of many components that cooperate to provide the desired functionality. This need for cooperation causes complex interactions between components, which makes developing cyber-physical systems difficult, especially systems whose component structure changes dynamically at runtime. We have created a formal, scenario-based specification method which makes it easier to develop distributed cyber-physical systems. We previously presented an approach for the distributed execution of such specifications based on naive and inefficient broadcasting. In this paper we propose a more efficient approach which uses the available network resources more economically.

Abstract Due to continuously rising electricity prices, the energy efficiency of production systems is an increasingly important factor in industrial manufacturing. One goal is therefore to reuse the braking energy of manipulator axes. The acceleration and deceleration phases of axes must be synchronized such that, ideally, the braking energy can be reused immediately within the system. In our current technique for the energy-efficient motion planning of concurrent movements of axes, we do not yet consider changing the discrete control logic to reorder movement sequences. This is difficult, since this reordering must not violate critical system requirements. In this paper, we outline a new technique for automatically synthesizing energy-efficient discrete controllers from a scenario-based specification of a production system, which we enrich with information about consumed and generated energy. Last, we provide an outlook on challenging open research problems.

[BibTeX] [Abstract] [Download PDF]

The development of safety-relevant systems in the automotive industry requires the definition of high-quality requirements and tests for the coordination and monitoring of development activities in an agile development environment. In this paper we describe a Scenarios in the Loop (SCIL) approach. SCIL combines (1) natural language requirements specification based on Behavior-Driven Development (BDD) with (2) formal and test-driven requirements modeling and analysis, and (3) integrates discipline-specific tools for software and system validation during development. A central element of SCIL is a flexible and executable scenario-based modeling language, the Scenario Modeling Language for Kotlin (SMLK). SMLK allows for an intuitive requirements formalization, and supports engineers to move iteratively, and continuously aided by automated checks, from stakeholder requirements to the validation of the implemented system. We evaluated the approach using a real example from the field of e-mobility.

Robots are found in most, if not all, modern production facilities and they increasingly enter other domains, e.g., health care. Robots participate in complex processes and often need to cooperate with other robots to fulfill their goals. They must react to a variety of events, both external, e.g., user inputs, and internal, i.e., actions of other components or robots in the system. Designing such a system, in particular developing the software for the robots contained in it, is a difficult and error-prone task. We developed a formal scenario-based modeling method which supports engineers in this task. Using short, intuitive scenarios engineers can express requirements, desired behavior, and assumptions made about the system’s environment. These models can be created early in the design process and enable simulation as well as an automated formal analysis of the system and its components. Scenario-based models can drive the execution at runtime or can be used to generate executable code, e.g., programmable logic controller code. In this paper we describe how to use our scenario-based approach to not only improve the quality of a system through formal methods, but also how to reduce the manual implementation effort by generating executable PLC code.

Executable business processes contain complex business rules, control flow, and data transformations, which makes designing good tests difficult and, in current practice, requires extensive expert knowledge. In order to reduce the time and errors in manual test design, we investigated using automatic combinatorial test design (CTD) instead. CTD is a test selection method that aims at covering all interactions of a few input parameters. For this investigation, we integrated CTD algorithms with an existing framework that combines equivalence class partitioning with automatic BPELUnit test generation. Based on several industrial cases, we evaluated the effectiveness and efficiency of test suites selected via CTD algorithms against those selected by experts and random tests. The experiments show that CTD tests are not more efficient than tests designed by experts, but that they are a sufficiently effective automatic alternative.
